Struct PathData 

pub struct PathData {
    pub verbs: Vec<PathVerb>,
    pub fill_rule: FillRule,
}

A resolution-independent path built from PathVerb segments.

Paths are the primitive used for arbitrary filled and stroked shapes. Build a path with the chaining builder methods, then pass it to DrawList::push_path or DrawList::push_stroke_path.

Fields

verbs: Vec<PathVerb>

The ordered sequence of drawing verbs that define this path.

fill_rule: FillRule

The fill rule used when rasterising filled versions of this path.

Implementations

impl PathData

pub fn new() -> Self

Construct an empty path with FillRule::NonZero.

pub fn with_fill_rule(self, rule: FillRule) -> Self

Set the FillRule on this path (builder-style).

pub fn move_to(&mut self, p: Point) -> &mut Self

Append a MoveTo verb.

pub fn line_to(&mut self, p: Point) -> &mut Self

Append a LineTo verb.

pub fn quad_to(&mut self, ctrl: Point, end: Point) -> &mut Self

Append a quadratic Bézier QuadTo verb.

pub fn cubic_to(&mut self, c1: Point, c2: Point, end: Point) -> &mut Self

Append a cubic Bézier CubicTo verb.

pub fn close(&mut self) -> &mut Self

Append a Close verb, closing the current sub-path.

pub fn is_empty(&self) -> bool

Returns true if this path contains no verbs.

pub fn bounds(&self) -> Option<Rect>

Conservative axis-aligned bounding box over all control and anchor points in the path.

Returns None if the path is empty. Note this is a control-point AABB, not a tight geometric bounds: Bézier curves can dip outside the control-point hull.

Trait Implementations

impl Clone for PathData

fn clone(&self) -> PathData

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PathData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PathData

fn default() -> PathData

Returns the “default value” for a type.

impl PartialEq for PathData

fn eq(&self, other: &PathData) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
